Power Generation

The SunFlower is a really interesting looking piece of technology, and I'm thinking of building one for power generation.

The question is, what is the most effective way to do so? My thought had been to use it for steam generation, and then use that steam to turn a Tesla Turbine. In the location I'd put this in on our off-grid land, we have access to water, but I was thinking of trying for a closed-loop water system so that once the steam runs through the Tesla turbine, it refills the reservoir and is reused in the SunFlower.

So, a few questions based on that. First, does this sound like a good method of power generation, or do you have other methods that you've found work well? And second, have you done any kind of testing as to what levels of power generation you could get out of this?
